I'm going to man up and say it... Fuel Injection does NOT have absolutely more gross power output than carbies do. In fact there was a Honda drag racer a year or so back that ran Webers on his NA car instead of injection as he found it produced MORE horsepower. EFI has the advantage of being continuously variable and adapt much more easily to changing weather than carbs. You could get carbs to run as well as efi, you'd also have to dyno tune your car every day before you drove it. Why do modern cars get more power you ask? Well because of 02 sensors and Knock sensors. Modern computer controlled cars that run efi and spark can push advance and fuel tables much closer to the ragged edge between max performance and detonation since the computer is keeping check on the works. The only way you can do that with carbies is with a knock amp and a dyno. Most people don't just have that sittin' around in their garage.

However, EFI cannot atomize fuel as well due to the location of the injector sitting literally on the intake port. Unless you're running injectors at the top of the air-horns (think F1), you will still get fuel falling out of atomization and a puddling effect on the intake port. In fact, most EFi systems acknowledge this and compensate for it. Compared to injector-on-port efi, webers have, and as far as I can tell, will continue to atomize fuel better.

Do carbs suck? no. They have their place.

The M104.980 3.0L engine already has a dizzy on the exhaust cam as well as an aluminium intake manifold. You could run MegaJolt (the spark only side of MegaSquirt EFI) triggering off the flexplate as normal through the dizzy or even through a wasted spark (you could probably run the cam with it too), and you could cut the alloy manifold and weld on some side-draft flanges. Et viola! A carbie M104 with a sweet sweet Weber carb sound on the top end.
